Title: Section 6-2.19 - Bathing beach design standards

6-2.19 Bathing beach design standards.

0.0 Introduction. These standards are to be used by public health officials, design engineers and architects, and the owners and operators of bathing beaches for the design of new or modified bathing beaches regulated by this Subpart. These standards are enacted to ensure adequate design and establishment of bathing beaches, reflecting current safety and sanitary requirements. These standards are applicable to all bathing beaches located on ponds, lakes, streams or other bodies of water in the State.

1.0 Definitions.

1.1 Bathing beach shall mean a bathing place, together with any buildings and appurtenances, and the water and land areas used in connection therewith, at a pond, lake, stream or other body of fresh or salt water which is used for bathing or swimming with the express or implied permission or consent of the owner or lessee of the premises or which is operated for a fee or any other consideration or which is openly advertised as a place for bathing or swimming.

1.2 Uniform Code shall mean the New York State Uniform Fire Prevention and Building Code, 9 NYCRR Subtitle S, Chapter I.

1.3 Adequate shall mean sufficient to accomplish the purpose for which something is intended, and to such a degree that no unreasonable risk to health or safety is presented. An item installed, maintained, designed and assembled, an activity conducted or act performed, in accordance with generally accepted standards, principles or practices applicable to a particular trade, business, occupation or profession, is adequate within the meaning of this Subpart.

2.0 Submission of plans.

2.1 General. Preliminary plans and the engineer's report should be submitted for review prior to the preparation of final plans. No approval for construction shall be issued until final, complete, detailed plans and specifications have been submitted to the permit-issuing official (PIO) and are approved. Documents submitted for formal approval shall contain sufficient information to demonstrate to the permit-issuing official that the proposed bathing beach, or improvements thereto, will meet the design standards specified in this section, and shall include, but not be limited to:

2.1.1 Detailed description of the watershed, with location and identification of all potential sources of contamination, including any anticipated future development.

2.1.2 Location of access roads, parking, buildings, water supplies, sanitary and storm sewers, electrical and telephone services and the proposed facilities relative to existing facilities.

2.1.3 Date, address, name, professional seal, and signature of the designing engineer or architect.
